170 Fahrenheit, and the oil is then poured State of New York, haveinvented certain new and useful Improvements in Aluminous Compositions,of which the following is a specification.

The basis of this composition is clay, and preferably that'charaoter ofclay found in some portions of Long Island and elsewhere I which has acontent of sulfur in the form V of free sulfur or some metallic sulfidsuch as .sulfid of iron. In any event, whether the sulfur is a naturalcontent, or whether the, same is added to the clay, it must be in acondition to combine with oilto v'ulcanize the latter. I

For some purposes, an effective compositionis secured by a mixture ofthe clay and vulcanized oil, but the mixtures in some proportions arenot valuable for certain urposes in consequence of the tendency 0 thecomposition to harden and become brittle at reduced temperatures, and inorder to obviate this objection I combine with the 4 ture so that itwill retain its aforesaid composition an additional proportion of oilwhich has been nitrated. By the addition of nitrated oil to theaforesaid.

composition I find that it is rendered more plastic and has greaterflexibility, and that it is not affected by a reduction of tempera-'plasticity at low temperatures'where otherwise. it would harden and beunsuitable for some purposes.-

In the manufacture of my improved c'omposition I'take a given quantityof nitric I acid of a .specificgravity of 1.4, and place it in areceptacle containing a 'cooling coil.

The acid is heated to a temperature of about I Witnesses:

slowly into the acid and the two are agitated together. In order toprevent the car- The oil is generally used in about equal proportions tothe proportion of acid employed but varies within wide limits. After themixture is efi'ected, the oil is separated from the acidwashed and apreparation of alkali is employed so as to neutralize any free acid andsecure the nitrated oil entirely free from any trace of acid. The oilemployed should be capable of vulcanization and any oxidizable oil ofthis character may be used, as,

for instance, linseed oil, castor oil, olive oil,

etc. The nitrated oil thus secured is added in any desired proportion,as from two per cent.,tofifty per cent, to the mixture of clay andvulcanized oil, theproportion depend ing upon. the degree of'plasticityand flexibility which the final composition should possess.

' Without limiting myself to the proportions set forth, I claim: I

1. A composition consistin of clay and vulcanized oil and nitrated 011as set forth. 2. A composition consisting of clay and vulcanized oil anda nitrated oxidizable oil as set forth.

In testimony whereof I have signed my name to this specification in thepresence of the subscribing witnesses.
